After installation of recent roblox studio update, studio instance i’ve been working on previously that had been running clean at high frame rate suddenly started bottlenecking between 15-25 fps. studio instance will open at 60fps and slowly degrade down to the bottleneck. bottleneck occurs extremely faster when utilizing native studio UI ( explorer, properties, material manager, etc)

another classic roblox studio update breaking the workflow. you aren’t alone here. what you are experiencing is almost certainly a UI rendering memory leak, likely tied to how studio’s backend (the Qt framework) handles widget redrawing for things like the Explorer and Properties panels.
when you interact with the native UI, it triggers a cascade of unnecessary redraws that completely eat up your CPU/GPU overhead, causing that slow degrade from 60fps down to 15fps.
until roblox engineers actually patch this bad build, try these workarounds to survive:
Force a different Graphics API: go to File > Studio Settings > Rendering. change your Graphics Mode from Automatic to Direct3D 11 or Vulkan. restart studio. sometimes an update breaks the automatic detector and it defaults to a terrible rendering API. Reset your UI Layout: corrupted docking configurations can cause infinite rendering loops. go to the View tab and click Reset View. Audit your Plugins: a rogue plugin might be aggressively polling or trying to update the properties window in the background, which drastically accelerates the UI memory leak. disable all plugins temporarily and see if the FPS still tanks.
it’s definitely not your PC’s fault. it’s just an unstable studio build. use these steps to mitigate it while we wait for a hotfix.
